stunnel was abandoned for Cygwin back in the fall. I've packaged the latest version for Cygwin (URLs below) and would like to maintain it.
stunnel is a program that allows you to encrypt arbitrary TCP connections inside SSL (Secure Sockets Layer). stunnel can allow you to secure non-SSL aware daemons and protocols (like POP, IMAP, LDAP, etc) by having stunnel provide the encryption, requiring no changes to the daemon's code. Changes since the last Cygwin release: - updated to version 4.20 - moved stunnel executable from /usr/sbin to /usr/bin, to comply with the Linux Filesystem Hierarchy Standard - added cygstunnel.dll - changed to cygport build method - new Cygwin maintainer Please note that, although libstunnel.so (i.e. cygstunnel.dll) is included in this package (as Corinna requested back in October; http://www.mail-archive.com/cygwin-apps@cygwin.com/msg17175.html), its use is undocumented AFAICT and so I haven't tried to test it. I guess that something like LD_PRELOAD=/usr/bin/libstunnel.dll should provide transparent proxy support for clients via stunnel, but I don't really know how or if it would work. If people want me to leave that in so they can test it, fine. If not, fine too and I'll take it out. Please review and, if the package is found suitable, upload.
